Quick change to cut costs Maillefer’s continuous type change (CTC) aims to significantly cut costs in medium voltage rubber cable production by allowing a change of tooling without stopping the line. Conventional type changes can be time consuming, but by installing CTC into the crosshead, type change times are significantly reduced, saving not only time but also materials and energy. Conventional type changes can demand hours of downtime and piles of scrap material, but type changes with CTC require only minutes with almost no cable loss. CTC is already widely used in XLPE medium voltage cable production around the world and is now being developed for rubber insulated medium voltage cables. Test runs have been carried out, including three changeovers with a 20kV cable. The test series was initiated with a conductor cross-section area of 240mm 2 and concluded with a 50mm 2 conductor. The cables were cured in nitrogen atmosphere. Based on an average of recent insulation material price levels, type change costs without CTC can be up to €5,000 per change and with CTC are only €75. CTC is designed to significantly reduce the overall downtime of frequent type changes, while not demanding heavy investments. Maillefer OY – Finland Website : www.maillefer.net
